I'm trying to decide if you are being serious? You have always seemed like a reasonable person as far as I can remember, so for now I'll go on the assumption that you're just being a bit sloppy.
Jesus isn't explicitly quoted as having endorsed the sanitation laws in the OT as far as I remember, but that is the argument from silence. He repeatedly endorsed the whole Law, and denying that is either ignorant or dishonest. As far as the dirtiness of Europe, you seem to be confusing the Church with biblical Christianity. The Church for a long time denied biblical laws of all sorts as pagan or Jewish, so they went backwards in time on sanitation science, but a quick perusal through the NT shows that biblical Christianity never made such distinctions. One more thing, the link you provided took me to John 13:10
which is quoted as This explains His point of view on bathing/washing; do you wash your hands after a bath?
Re your point about Roy Moore's connection to Christianity, you're right, there are probably an awful lot of people who are only voting for him because of the C by his name, but it's a bit much to say he would get NO support.

The Bible was lightyears ahead of other religions, the church, and the secular world in terms of sanitation and health. The Bible actually commands bathing and washing, among other sanitation laws, while the Jews had/have other extra washing rituals. In that context, Jesus' statement means something different from how you took it; He is just saying that rituals and excessive washing are unnecessary. But at any rate, what does this have to do with Roy Moore?

Dude- learn some history.
The place now called "Israel" was an invasion of the ME. Jews & Christians lived there peacefully with Muslims until their land was taken by the Brits.
This is no different than deciding that New England needs to be given back to the Indians & throwing everyone there out with no regard to their rights & property.
